Impressive views, even if you're just starting out
The Skywatcher N 406/1800 immediately gives you that ‘wow’ feeling. The huge 406 mm mirror captures so much light that faint nebulae, galaxies and clusters suddenly come into clear view. You see structures that are normally only visible in photographs. Your image remains clear and sharp even when you magnify strongly.

More light, more details
A 16-inch mirror really does something special. Your image becomes more than three times brighter than with a 10-inch scope. That means you see more contrast, more shape, more structure.You recognize at a glance dark dust trails in Andromeda, fine filaments in Orion and subtle details in globular clusters.For planets, you see sharp edges, clear cloud bands and tiny moons. This keeps every target interesting, whether you're chasing planets or going deep into space.

FlexTube: large, yet easy to carry
The retractable FlexTube design makes the tube surprisingly compact. You slide it in, lift it up and take it with you easily.Once outside, slide the rods out to the right length. The focal point remains stable, so you're ready to look quickly.
GoTo searches and tracks automatically
The GoTo function does the heavy lifting for you. You select an object from the database of 42,900 targets and the telescope aims and tracks for you, keeping your object in focus, even at high magnification. Handy if you're just starting out, but also nice if you just want to look relaxed without having to keep adjusting.
Strong motors for smooth movement
The servo motors move smoothly and quietly. You can fine-tune slowly or drag quickly to the next spot.
This keeps your image calm and easy to follow, even when centering a faint deep-sky object.
Ready to observe
The tube is sturdy, the rocker box is stable, and the included viewfinder gets you in the right direction quickly.
With the 25 mm and 10 mm eyepieces, you can start right away and try different magnifications.
